While I was coding the Elemin Theme (a responsive WordPress theme that I recently designed), one of the challenges that I faced was to make the embedded videos elastic. Using the max-width:100% and height:auto trick works with native HTML5 video tag, but it doesn't work with embed code using iframe or object tag. After hours of experimenting and Googling, I finally found a trick on how to achieve this. If you are creating a responsive design, this simple CSS trick will come in handy. View the final demo and resize your browser window to see it in action.

Screen resolution nowsaday ranges from 320px (iPhone) to 2560px (large monitor) or even higher. Users no longer just browse the web with desktop computers. Users now use mobile phones, small notebooks, tablet devices such as iPad or Playbook to access the web. So the traditional fixed width design doesn't work any more. Web design needs to be adaptive. The layout needs to be automatically adjusted to fit all display resolution and devices. This tutorial will show you how to create a cross-browser responsive design with HTML5 &CSS3 media queries.

CSS2 allows you to specify stylesheet for specific media type such as screen or print. Now CSS3 makes it even more efficient by adding media queries. You can add expressions to media type to check for certain conditions and apply different stylesheets. For example, you can have one stylesheet for large displays and a different stylesheet specifically for mobile devices. It is quite powerful because it allows you to tailor to different resolutions and devices without changing the content. Continue on this post to read the tutorial and see some websites that make good use of media queries.
